%X Introducing currently vehicular ad hoc networks (VANETs) routing algorithms, the paper proposed a novel opportunistic routing algorithm based on triangular fuzzy number. The algorithm analyzed and calculated these factors as objective functions, including the distance between the forwarding and the destination, the direction to the destination, the forwarding velocity vector, retransmission numbers and traffic flow conditions. It adopted an entropy weight coefficient method to determine each factor weight. In routing process, the node would select greedily the highest vector-valued node to propagate packets, and use a store-carry-forward opportunistic strategy in spare networks. Simulation results indicate that the algorithm can apply better to various VANETs scenarios.
